are the fan leaves suposed to fall off?

so my plants are in their 4th week of flowering and alot of fan leaves are turning yellow and falling off..it seems like its doing it where their blocking light from the buds..or maybe it seems like that because i dont want my babies to be sick lol...are they supposed to fall off?

Its normal for some to fall off. But if its alot then probably you need some nitrogen .Usually its normal during the 4th week for your plants to need a boost of Nitrogen
